T0 (tZZ whom it may concern:

Be it known that I, ERNEST I-1.VoGEL,a citizen of the UnitedStates, residing in the city of New York, borough of Brooklyn, county of Kings, and State of-New York, have in vented certain new and useful Improvements in Mechanical Movements, of which the followingis a specification sufiicient to enable others skilled in the art to which the invention appertains to make and use the same.

My invention relates to means for convertingrotary into intermittent reciprocatory motion, as hereinafter set forth, the object being to attain a uniform even motion as compared with the ordinary crank-motion and also to attain the transmission of the maximum of power within prescribed limits.

The invention consists in the construction and arrangement of parts hereinafter described and claimed specifically.

My improvements-are applicable to power stamping-presses, printing-presses, 650., in which alternating operations are performedas, for instance, a stamping-press in which blanks are subjected successively to the action of two dies.

In the accompanying drawings, Figure l is an elevation of my improved mechanism, the shaft being shown in section upon plane of line 1 1, Fig. 2; Fig. 2, a section upon plane of line 2 2, Fig. 1; Fig. 3, a similar view illustrating the operation of tripping; Fig. 4, a section upon plane of line 4 4, Fig. 1; Fig. 5,

a similar view showing the parts reversed in position as compared with Fig. 4; Fig. 6, an elevation of the carrier-plate; Figs. 7, 8, and 9, diagrammatic views illustrating the different positions of the actuating-pinion with relation to the transmitting rack-plate. Figs. 10, 11, and 12 are sections upon plane of line 10 10, Fig. 4. Fig. 13 is an elevation of the inner side of the eccentric disk; Fig. 14, an elevation of the opposite side thereof; Fig. 15, an elevation of the inner side of the reversing-disk; Fig. 16, a perspective view of the clutch-lever. Fig. 17 is a view similar to Figs. 2 and 3, showing a modification in the tripping mechanism. Fig. 18 is an elevation of the inner side of the clutch-plate; Fig. 19, a side elevation of the starting-disk; Fig. 20, an edge View.

In the drawings, A represents the transmitting rack-plate to be reciprocated, it being formed at one end a to receive a wristpin or other mechanical expedient for connecting it pivotally to the part to which it is desired to transmit motion. The rear portion of the transmitting rack-plate A is formed with a longitudinal slot 0., upon the inner edges of which are formed the parallel rackbars I) 17'. These rack-bars b b are each formed with inner and outer rows of teeth I) b and 1) 12 The inner edges of the racks b b are formed with recesses or depressions b b b b", respectively, near their opposite extremities by the removal or omission of the rack-teeth at these points.

0 is a carrier-plate provided with rollers 0, upon which it is supported on the upper and lower edges of the rear portion of the transmittin g rack-plate A,which edges extend parallel adjoining and beyond the racksbb, substantially as shown in Fig. 1 of the drawings.

The carrier-plate O is also formed with journals or studs 0 cflupon which are mounted pinions d and d respectively, engaged with the rack-teeth b and b These pinions d d carry the starter-disks e 6, formed with the shoulders e 6 respectively, the function of which is hereinafter to be described.

E is the power-shaft, continuously rotated by any suitable means. A; is a pinion rigidly secured to said shaft E in line with the racks b b and adapted for engagement alternately with the racks b b. Adjoining the pinion 7c and also rigidly secured to the shaft E in the same plane as the starting-disks e e is the reversing-disk f, carrying the contact-roller or equivalent f for engagement with the shoulders e e on the said starting-disks e e. The only other operative part of the device secured rigidly to the power-shaft E is the clutch-operating disk G, which may constitute a portion of the hub of the power-pulley, if desired, as indicated in Fig.15. This clutch-actuating disk G is formed with shoulders g g for engagement with projections h h upon the outer face of the clutch-plate H,

mounted directly upon the shaft E, if desired, instead of upon the hub or sleeve of the eccentric disk, the essential feature in this connection being that the clutch-disk II and the eccentric disk I shall be free to rotate under certain conditions independent of the clu tchactuating disk G and reversing-disk).

Studs h project from the inner side of the clutch H and pass through perforations 2" t in the eccentric disk I and into recesses 0 in the carrier-plate C under normal conditions under the pressure exerted by the springs g through the plungers g upon the outer side of the clutch-disk H. The clutch-disk II is forced back to release the studs h from the recesses 0 against the resistance of the springs g by means of a trip-lever J when the latter is brought into contact with one of the tripping-toes or equivalent devices L L. This tripping-leverJ is situated mainly in the recess h formed for its reception in the inner side of the clutch H, its outer end projecting sufficiently to engage with either of the tripping-toes L L. The outer surface of. the eccentric disk I is beveled slightly, as at 1 7: to receive the outer end of the tripping-lever J when depressed.

is the eccentric upon the inner surface of the plate I. On this eccentric is mounted the annular bearing m, which latter is of a diameter corresponding to the width of the longitudinal slot at in the transmitting rackplate under the action of the eccentric, so as to bring either one or the other of the'sets of racks b 19 into engagement with the pinion 70, as the case may be.

In Figs. 2 and 3 both reversing trippingtoes L L are shown as secured to the transmitting rack-plate A directly, although this is not essential, since they may obviously be situated upon any stationary part so related to the motion of the rack-plate A as to effect the tripping of the lever J at the end of each stroke, or obviously they may be arranged adjustably with relation thereto, as indicated at L in Fig. 17, in which case the reversing of the tripping-rod A may be delayed and controlled indefinitely or definitely by the aid of suitable automatic mechanism for advancing and receiving the tripping-toe L. a

The operation is as follows: Suppose, by way of illustration, that the transmitting rack-plate A has completed its retractile or left-hand stroke, bringing the tripping-toe L into contact with the clutch-lever J, and thereby forcing back the clutch-disk II, so as to withdraw the studs h from the recesses c in the carrier-plate C, it being of course'understood that the actuating-pinion 7c isbetween the recessed surfacesb b and out of engagement with either of the series of rack-teeth b 19 Under these conditions the continued rotation of the shaft E carries the studs h beyond the recesses 0 so that the clutch H is held out of engagement with the carrierplate until the completion of one-half a revolution of the shaft E. During this one-half revolution of the shaftE the eccentric 2' act ing through the contact-roller f, raises the transmitting rack-bar A sufficiently to bring the teeth in the wheel 7c into alinement with the series of teeth 12 upon the lower rack I). Just prior to the completion of this one-half revolution the contact-roller f upon the 136-; versing-disk f encounters the shoulders e upon the starting-disk e, thereby rotating the latterand the wheel 0 sufficiently to start the transmitting rack-plate A upon its forward or right-hand stroke, the wheel is immediately meshing with the teeth I)", and thus insuring the completion ofthe forward stroke. Upon the completion of the forward stroke, bringing the wheel 7c between the depressed surfaces 12 b the end of the tripping-lever J encounters the tripping-toe L, said lever J having obviously been reversed in position by the half-revolution of the shaft E, as described, so as to project toward said trippingtoe L, upon encountering which it releases the studs h from the recesses c in the carrier 0, thereby rotating the eccentricso that it lowers the transmitting rack-plate A sufficiently to bring the teeth of the wheel a into alinement wit-h the teeth in the rack-barb,

the contact-rollerf upon the reversing-diskf in this case striking the shoulder e on the starting-disk e, thereby causing the wheel d to act upon the teeth 6 tostart the transmitting rack-plate A in its retractile movement, at the same time releasing the trip-lever J from the tripping-toe L, so that the studs h are free to again enter the recesses c in the carrier-plate C under the impulse of the springs g in the clutch-actuating disk G. These operations are repeated automatically at the end of each stroke, provided the tripping-toes L L are rigid or permanentin position. If a tripping-toe, as L", Fig. 17, is withdrawn temporarily orotherwise from position, it is obvious that when the wheel it reaches a position, say, between the depressed surfaces 12 b the studs It will continue to engage the recesses c in the carrier-plate O and will thereby hold the eccentric plate against rotation until such time as the tripping-toe L" is brought forward automatically or otherwise to engage the tripping-lever J and release the studs h, as hereinbefore set forth. In the meantime the shaft E and pinion It will continue to rotatewithout act-ing upon the transmitting rack-plate A.

It is obvious that, if preferred, the eccentric i may be made of sufficient diameter to fill the slot 0/ in the transmitting rack-plate A, thereby dispensing with the annular contactroller m, although I prefer ordinarily to use the latter.

The rollers c on the carrier-plate O are bearing upon the parallel edges of the transmitting rack-plate A to preserve the alinement of the parts. In the construction shownin the drawings the parts are timed sothat the shaft E makes one revolution. between the extremes of motion. In other words, there are three revolutions for each complete reciprocation of the transmitting rack-plate-that is to say, one-half a revolution in reversing, a whole revolution in the forward movement, one-half a revolution in reversing, and one whole revolution in the retractile movement. It is obvious that by lengthening the rackplate any desired number of revolutions of the shaft E may be provided for between the reversal at either end of the stroke, provided always that the number of teeth employed represents a definite number of complete revolutions.

What I claim as my invention, and desire to secure by Letters Patent, is-
